先天性心脏病是指任何结构性的defect of the heart and/or great vessels (those directly connected to the heart) present at birth. Congenital heart disease affects all aspects of life, including physical and mental health, socialising, and work. Most patients are unable to exercise at the same level as their peers which, along with the awareness of having a chronic condition, affects mental wellbeing.

"Having a congenital heart disease, with a need for long-term follow-up and treatment, can also have an impact on social life, limit employment options and make it difficult to get insurance," said Professor Helmut Baumgartner, Chairperson of the guidelines Task Force and head of Adult Congenital and Valvular Heart Disease at the University Hospital of Münster, Germany. "Guiding and supporting patients in all of these processes is an inherent part of their care."

All adults with congenital heart disease should have at least one appointment at a specialist centre to determine how often they need to be seen. Teams at these centres should include specialist nurses, psychologists and social workers given that anxiety and depression are common concerns.

Pregnancy is contraindicated in women with certain conditions such high blood pressure in the arteries of the lungs. "Pre-conception counselling is recommended for women and men to discuss the risk of the defect in offspring and the option of foetal screening," said Professor Julie De Backer, Chairperson of the guidelines Task Force and cardiologist and clinical geneticist at Ghent University Hospital, Belgium.

Concerning sports, recommendations are provided for each condition. Professor De Backer said: "All adults with congenital heart disease should be encouraged to exercise, taking into account the nature of the underlying defect and their own abilities."

The guidelines state when and how to diagnose complications. This includes proactively monitoring for arrhythmias, cardiac imaging and blood tests to detect problems with heart function.

Detailed recommendations are provided on how and when to treat complications. Arrhythmias are an important cause of sickness and death and the guidelines stress the importance of correct and timely referral to a specialised treatment centre. They also list when particular treatments should be considered such as ablation (a procedure to destroy heart tissue and stop faulty electrical signals) and device implantation.

For several defects, there are new recommendations for catheter-based treatment. "Catheter-based treatment should be performed by specialists in adult congenital heart disease working within a multidisciplinary team," said Professor Baumgartner.
